residingf in the cityof Baltimoreg State of lvllaryland, l have invented certain new and useful Irn`}`)rovements in Marking-iMachines7 of which the following isa specification.

The present invention relates ,to'afstampr ing .machine particularly adapted v:for use in the marking of'checks,y the` object of the invention being tol prdduce a-'simpliliedapparatus of' increased. utility which can be manufactured conveniently in large numbers atafniinimurnoutlay.l p 7 K Described in general terms thel machine consists of'a type carryingforprintingmem ber', fa guide `for the same which be a trackror Way, an yinkingmember orpztd `with a coperating guide which: may alsobea mick. or Way, intersecting the'line or .piane of the rst-namedfgu'ide; and two connectinglrods Whichlina general Way are` oppo`- sitely disposed and togglewise related or pivotally connectedrand actuatedfrom saidv pivotal connection or toggle joint by moving the pivot or jointon a predetermined path,

imparting to the printing member an alternate short and long stroke. 'lhelpadis` reciprocated on its-intersectingpath and inter-` cepts the printing member and inks the `type at the end of theshort stroke oflthe latter and movesv out of the -path ofV the printing Vmemberl tov-*provide4 for the printing 'or'longstroke o'f the printing member.

More particularlyg` this'fis accomplished 'by moving-said pivotor'yvjoint throughand by vthe dead point ofv the connecting; rnd Whicliqactuates the printingvmember' by a Vshort'arc" .or distance on one sida-"5.y er, when the pad is advanced into itheV pathl of the:

printing` ineniber;` on thel short stroke; and by acomparatively long arc ordistance on the other sidey when thepad is'withdrawn and theprintindmeniber descends forthe longv or printing stroke.-

Preferably the guide `sects the-pathiofv the printingmembr substantially 'at right angles,4 lis" inclined inthe ,direction from' whichithe printing member approaches itfcand while" thev pad itself, is

supported at right angles to i the direction of motionof= the printing member, the `two members-approach each oth'e'gon theiinfking .stroke ati an; angle-off; 56;

Referring tothe the` printing member Byconsists of a frame 15 which may be most conveniently cnt or stamped from a single Vfiat piece of sheet metal, the same being Banged or turned at right'angles at thel bottom edge at `16 and preferably being supplied With an edge fac- .mg 17fofp'aper, fiber or leather to engage the Ways, giving a noiseless operation. y.To

the bottom flange 16 is Ysecured a type-carrying member 18 Vshown in detail in its prefer-red form atfl) inFigsfll and .-5. This plate or type lcarrier hasits edges folded over as indicated at 19`to receive the type.,V plate'QO and has a fastening device for the latter. There is a transverse spring plate` Vor band fll extending transversely of the: type carrienon top, spaced up therefrom,r` the sameserving as aholderfor a ball'22 which engages asocket 23 in the band 21 andl an'opening 24 in the 'carrier-plate, so that asectlon of the ball extends through indentation Vor, hole in thev type plate.

It will be apparent that the ball-is mounted .to .yield so that thetype plate While held frictionally, can be Withdrawn when sulicient pressure 'is applied.` Thejmounting of the crosshead pin is illustrated in detail in Fig, 6, the same consisting' of a band or strip 26gbent in theform Vof a shallow for shortf U, the vbase ofl the U being secured transversely? to the top'of the frame or plate-15. The'ends of the arms ofthe U are bored'or aperture'd at '27 to form'journal bearings .for the pin v`1Q. The lattter 1s heldin position bymeansof'a collar 28 secured to thepin a short distance from one end, a Collar 29` secured to the pin near the center' to position the connecting rod, al

However, the specific terms herein are used descriptively rather than in their limiting sense, the scope of the invention beingl defined in the claims:

lVhat I claim and desire to secure by Letters Patent is kl. In a printing or marking machine, in combination` a printing member, guiding means therefor, confining it to a predetermined path, an inking member, guiding means therefor, confining it to a fixed path,

oppositely disposed, togglewi'se"` related connecting rods, one actuating eachsaid mem- Y ber, means for moving the adjacent ends of theconnecting rods on a fixed path through and by the dead center of the connecting Y rod which actuates the printing member, giving the latter an alternatelong and short stroke, moving the inking member into the path of the printing member at the end of the short stroke, and removing it from the path of the printing member diiring the.

long stroke. Y

2. In a printing and marking machine, in combination a reciprocating printing mem ber, guiding means for the same, a reciprocating inking member and` a guide therefor, the path of the two members being thus closed to intersect an oscillating crank shaft parallel to the line of intersection of the planes of said paths, a Aconnecting `rod for each said member actuated-from said shaft,

y the crank being so placed relatively to the pathof the printing member that it swings A moves through unequall arcs on each side of said dead point, giving an alternate long Vand short stroke of the printing member,

the inking member being moved by its conthrough the dead point of'said member and necting rod into the path of the printing member during the long stroke of the latter and out of the path of thek printing member during its short stroke. f

8. In a. printing or marking machine, in combination a printing member, guiding means for the same, lpermitting it to move on a fixedpath, aninking member, guiding means for the same permitting it to move on a fixed path, the two paths intersecting,

a connecting rod for each said-member, a

.shaft actuating said connecting rods, the crank pin radius of the connecting rod which actuates the'printing member being so related to the path `of the latter that it swings by unequal arcs on each side of the dead center ofthe connecting rod of the printing member, the connecting rod carrying the inking member being moved substantially on one side only ofits. dead center" so that while the printing member has along, '-Y

and short stroke, the inking member has a single stroke which moves it into the path of the .printing member at the end of the short stroke and out of the path of the printing member at the end of the long stroke. V
